When working with single xml files and while building specific XML configurations/file detection, it would be nice to see what xml configuration is being picked-up while opening marked-up files. It's true that it could always be assessed 'ex-post' by looking at the sdl:filetype-info code piece inside the created sdlxliff file, still, I believe that having a quick and prompt idea - and confirmation - of what filter settings are being selected for file opening would be really helpfull and productive.
